The Water Cycle

Lesson 3.3 Earth’s Spheres

Multiple Choice

Which of the following processes in the water cycle involves the transformation of liquid water into water vapor?

• Evaporation

• Condensation

• Precipitation

• Infiltration

Nutrient Cycling

•Matter cycles through the environment.

•Matter can be transformed, but cannot
be created or destroyed.

•Nutrients, matter that organisms require
for life process, circulate throughout the
environment in biogeochemical cycles.

Lesson 3.4 Biogeochemical Cycles

Did You Know?Organisms require several
dozen nutrients, such as nitrogen, phosphorus,
and carbon, to survive.

Multiple Choice

Matter can only be:

• Created

• Destroyed

• Transformed

The Carbon Cycle

Lesson 3.4
Biogeochemical
Cycles

Multiple Choice

Fossil fuels are part of the carbon cycle because, when burned, they release:

• Consumers

• Decomposers

• Detritivores

The Nitrogen Cycle

Lesson 3.4
